To get fans hyped for his big movie comeback, Charlie Sheen shared some action-packed pix from the set of the upcoming Roman Coppola-directed film, A Glimpse Inside the Mind of Charles Swan III.

The movie centers on an arrogant ladies' man that hits rock bottom and suffers through nightmares with a moral lesson -- sound familiar?

Costarring Sheen's Rushmore buddies Jason Schwartzman and Bill Murray, as well as Patricia Arquette and Audrey Plaza, Charles Swan is set for a 2012 release.

The Major League star couldn't help but take a jab at his former employers over at Two and a Half Men, posting a pic featuring an on-set explosion with the caption: "This is at least TWO AND A HALF times more fun than my last gig..!)".
